C#基于硬件ID创建一个唯一的ID

我正在创建一个特定于机器的许可证。许可证基于以下项目：

1. MAC地址
2. CPU序列号
3. 驱动器0的计算机卷序列号

我假设，如果3中的2个匹配，那么我的许可证是有效的。因此，可以获得新的网卡，并且许可证仍然有效，等等。

这是一个好方法吗？还是我会遇到不匹配或不定期更改的问题？

我正在尝试获取计算机的唯一标识符，以便验证许可证。

请告诉我这看起来怎么样，或者你是否有更好的解决方案！

再次感谢！

**这是我想出的**

我最终只使用了VolumeSerial、CpuId和VideoControllerDescription。

    public enum HardwareProfileComponents
    {
        ComputerModel,
        VolumeSerial,
        CpuId,

                             {HardwareProfileComponents.ComputerModel.ToString(), GetComputerModel()},
                             {HardwareProfileComponents.VolumeSerial.ToString(), GetVolumeSerial()},
                             {HardwareProfileComponents.CpuId.ToString(), GetCpuId()},
                             {HardwareProfileComponents.MemoryCapacity.ToString(), GetMemoryAmount()},
                             {HardwareProfileComponents.VideoControllerDescription.ToString(), GetVideoControllerDescription()}
                         };
        return retval;

    private static string GetVideoControllerDescription()

            return oReturn["Description"].ToString().Trim();
        }
        return string.Empty;

        var disk = new ManagementObject(@"win32_logicaldisk.deviceid=""c:""");
        disk.Get();
        string volumeSerial = disk["VolumeSerialNumber"].ToString();
        disk.Dispose();
        return volumeSerial;
    }
    private static string GetCpuId()

        var managClass = new ManagementClass("win32_processor");
        var managCollec = managClass.GetInstances();
        foreach (ManagementObject managObj in managCollec)
        {
            //Get only the first CPU's ID
            return managObj.Properties["processorID"].Value.ToString();
        }
        return string.Empty;
    }
